* [chore] Refactor HTML templates and CSS * eslint * ignore "Local" * rss tests * fiddle with OG just a tiny bit * dick around with polls a bit more so SR stops saying "clickable" * remove break * oh lord * don't lazy load avatar * fix ogmeta tests * clean up some cruft * catch remaining calls to c.HTML * fix error rendering + stack overflow in tag * allow templating attributes * fix indent * set aria-hidden on status complementary content, since it's already present in the label anyway * tidy up templating calls a little * try to make styling a bit more consistent + readable * fix up some remaining CSS issues * fix up reports
